| Abstract: | The influence of squeeze casting on cup-shaped ZA27 alloy castings with high ratio of height to thickness (M=7) was investigated. The effect of difference of mechanical properties in different parts of a casting by pressure is compared. With the increasing of the pressure, the mechanical properties is increased and the microstructure is refined. |
